"The job is to do pavers and fake grass front and backyard after few months weeds coming on the fake grass and pavers. Vinny landscape said its normal. My neighbor has turf grass but no weeds coming up. I'm holding $500 of payment so they fix it. They the best they can do is to spray the weed and they have to do it every 6 months and I have to pay. The reason I put pavers and fake grass us to avoid the weeds. So the project is useless."

"CHI has done an excellent job for me and I recommend them without hesitation for any remodeling work. Here's why: My job started out with an entry door replacement, evolved into a pantry expansion, and finally finished with an entire kitchen countertop replacement. I was very pleased with how they worked, the materials they used, and the attention to detail in the workmanship. And they were very responsive, communicated well and frequently, and checked in regularly to make sure the job was getting done right and on time. Each of their craftsmen were highly skilled, knew what they were doing, and didn't cut any corners. And each one was friendly and courteous to boot! I very much appreciated their attention to protecting the rest of the house, and they cleaned up the jobsite every single day at the end of their work day. Remodels are disruptive, no matter what. But this was about the least painful I've experienced. I have worked with a lot of contractors. CHI is a 10 out of 10."

"Would dodge the question when i asked for a contract and never wrote one out, broke 2 of my lighting fixtures (they replaced these), 2 window panes (they replacedone with plexiglass which is plastic and denied the other one), got paint everywhere including my front steps, left a truckload of garbage after saying they'd remove all of it, left asbestos everywhere, destroyed $500 worth of crown molding by cutting it wrong, and left beer bottles that they were drinking on the job in my sink. I'm afraid to have anyone work on my house ever again at this point."

"Ben and his team completed work on my condo and I could not be more pleased with the results. I tasked them with a two bathroom remodels, kitchen sink replacement, and the creation of new sliding doors between my office and the master bedroom. Ben, Marcus, and Pete were prompt, professional, and very considerate of my time and space. Of note is Ben's candor when it came to design ideas, and expense. He advised that several of my ideas weren't worth the money, and suggested more cost effective alternatives, which I really appreciated.

Guest house building services FAQs
In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.
Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.
When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.
How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.
Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.
No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
